Remodelling and extension to a 1950s suburban detached house

A single storey extension has been added to the rear and side of the existing house along with the rebuilding of the second floor changing the roof-scape from double hip to gable in order to obtain more useable floor area. Planning restrictions dictated the size, form and materials of the dormer.

The rear extension, built off a beam and block floor, opens onto a new large patio which is flush with the ground floor of the house with steps that lead down to the large garden.

A band of glazing running up the wall and across the roof delineates the extension from the existing main house and allows light into the centre of the ground floor.

The rear extension consists of a steel frame with timber studwork infill, fibre cement rain screen cladding and a green roof. The existing ground and first floors were completely remodelled but with detailing to match the original in contrast to the new areas which incorporate shadow gap detailing in order to achieve a clean modern look. This approach also allows the history of the development of the house to be appreciated.
